Fix Teledahn and Kemo Camera Issues

This fixes the camera getting stuck in the Teledahn upper shroom and avoids introducing a regression in the Kemo journey cloth link-in cameras.

Turns out, it was an artifact of us suspending the simulation during links and partly because of Cyan's late adding of the avatar controller to the sim. Previously, the avatar would be added to the sim after xJourneyClothsGen2 fixed the camera stack, so PhysX would brick it for us. Now, we add the avatar as soon as the age data is loaded. This causes the camera stack to be populated with whatever garbage PhysX decides on, then xJourneyClothsGen2 is free to set the real stack after we get all the SDL from the server.
